To turn on the speaker, press and release the Power button, pointed out by the yellow arrow the last picture.

The small lamp in that button should then light, as we see next, and the speaker should make its startup sound. If it does not, then the battery could be completely dead.

Press and release the center areas of the Volume UP and Volume DOWN buttons at the same time. Find these areas in the picture shown next.

When you press these buttons together, the speaker makes one to four “blunk” sounds to tell you how high the battery is. Four blunks means that the battery has between 75 and 100 percent charge. Three blunks, and the battery has between 50 and 75 percent charge. Two blunks denotes that you have between 25 and 50 percent charge in the speaker’s battery. And finally, one blunk means between 0 and 25 percent charge.

The Number of Blunks Tells The Story

Now since the Wonderboom 3 plays for up to fourteen (14) hours on a full charge, you can estimate based on the number of blunks you get, approximately how much play time you have left. Four blunks means that you have between 10.5 and 14 hours left. Three blunks means between 7 and 10.5 hours. Two blunks means between 3.5 and 7 hours. And one blunk means that you have less than 3.5 hours of playing time to go before the speaker dies.
